I’m upgrading an app to Spring Boot 2 and for some reason it no longer registers the property files as they were before. My project is setup into a series of modules:

  <modules>
    <module>service-api</module>
    <module>resource</module>
    <module>war</module>
    <module>integration</module>
    <module>tests</module>
    <module>docs</module>
  </modules>

Before upgrading to SB2 my property files were read without issue from the resource module, which was laid out like this:

When I run the application using this method:

@EnableAsync
@EnableFeignClients
@SpringBootApplication
public class IgipDealingApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(IgipDealingApplication.class, args);
    }
}

I get the error Could not resolve placeholder 'us.comCache.serviceUrl' despite this property existing in the property file application-DEV.yml.

I’m running the application with the dev profile and this is reflected on the logs on startup with The following profiles are active: dev but it doesn’t fix the issue.

I’ve tried moving the properties folder to the resource directory of the module that uses it and this doesn’t work. However, if I create an appplication.yml in the root of that resource directory with the property it registers:

Am I missing anything?
